I don't know of any specific way to do it. Though I would mention that
you could just do "bzr log" versus "svn log". They won't line up
perfectly, but it would probably be easier than doing a manual checkout
each time.

As for '20 revs behind', I would guess this is because of how bzr vs svn
handle 'merged' revisions. I don't know how you were using your
repository, but consider a case like:

 A
 |\
 B |
 | |
 | C
 |/
 D

In SVN, this would be:
 A 1, B 2, C 3, D 4
In bzr, it would be
 A 1, B 2, C 1.1.1, D 3

It will only cause problems if you somehow filter/mutate the svn
repository without getting rid of the bzr properties.
